Answer:

Charge= 1.8 x
10^(10) C

Step-by-step explanation:

Using the formula Charge= Current x Time

Q= IT

Current is measured in Ampere(A).

Current = 250 MA where M represents Mega(
10^(6))

Hence, Current = 250 x
10^(6)

Time= 1.2 x 60 (Conversion from minutes to seconds)

⇒Charge= 250 x
10^(6) x 1.2 x 60 =1.8 x
10^(10) C
